CAUTION:


  • A005PDGC22
    *a Heavy object exceeding the capacity of the engine lifter

    Because the weight of the engine with transaxle assembly is extremely heavy, make sure to follow the work procedures described in the repair manual.

  • If work is not performed according to the procedures described in the repair manual, there is a danger that the engine lifter could drop and components could fall down.


  • A005OU6C12
    *a High temperature areas

    Do not touch the engine or exhaust manifold converter sub-assembly when they are hot.

  • Touching the engine or exhaust manifold converter sub-assembly when they are hot could result in burns.


  • A005Q4U

    Never perform work on fuel system components near any possible ignition sources.

  • Vaporized fuel could ignite, resulting in a serious accident.


  • A005Q9J

    Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.
